Abstract
The utility model is a digital and intelligent feedback thread grinding compensation device. A grating reading device and a correction mechanism are arranged at the grinding device. A step motor is arranged at a shell of the correction device, and a ballscrew unit is arranged inside the shell. A ballscrew of the ballscrew unit is axially fixed and is connected with an output shaft of the step motor via a coupler. A nut of the ballscrew unit is fixed circumferentially, and correlates with a swaying rod arranged at a nut of a master screw of an original machine tool. The grating reading device is a grating reading head arranged at a principal axis of the grinding device. A workpiece to be processed is detected dynamically, and compensation data, which are formed based on the final precision, are input into a datasheet of a memorizer of the feedback correction device. When the workpiece is processed, ballscrew errors of corresponding points in the memorizer datasheet are taken out with a position signal of the principal axis. After the processing, the step motor drives the drive device to cause axial micro-movement of a workbench and correct the thread precision of the screw. The utility model can obviously increase the grinding precision of a ballscrew product, reduce the waste rate and the cost, promote the productivity, increase the economic benefits and promote the manufacture level of other machinery.
Description
Technical field:
The utility model relates to a kind of digital intelligent feedback thread grinding compensation arrangement, eliminates error when being used on grinding machine the grinding threads of lead screw.
Background technology:
Leading screw belongs to thin and long shafts part, and rigidity is very poor.In order to guarantee that leading screw in use has higher precision stability, after roughing, carry out surface hardening in the actual processing, carry out accurate grinding at last.The thermal deformation that grinding heat causes in the Grinding Process is one of important errors source of leading screw processing, and these have all increased the difficulty that improves the leading screw machining accuracy.For improving the machining accuracy of part, generally adopt error prevention and two kinds of measures of error compensation.The error prevention is exactly in manufacturing process system, consider to reduce the generation of error from aspects such as lathe, cutter, technology and materials, but along with the raising of required precision, the difficulty of this approach is also increasing as far as possible, the raising of precision is restricted, and cost is also very big.Error compensation is to proofread and correct the error that exists in the system of processing by custom-designed error compensation system, reduces error output, and this is an economy and practical processing approach.But early stage error compensating method mainly is by the mechanical checkout chi, adopts artificial compensation's control.Operating personnel repair by the leading screw error curve after processing and scrape and adjust the mechanical checkout chi, thereby reach the purpose of error compensation.Though this method can compensate the static geometric error of falling most of lathe, then can not effectively compensate for circular error and localized accumulated error.Laser-grating feedback compensation device, grating-grating feedback compensation device, appearance grid-induction synchronous feedback means for correcting and grating-magnetic grid feedback compensation device or the like, though can revise at random in real time to the workpiece local error, also obtained certain effect, but because processing environment is abominable, make measuring system stability be restricted, the effect of feedback compensation is had a greatly reduced quality.Because measuring system is just measured the lathe transmission chain error, can't measure error, alignment error, manual operation error that grinding heat in the process (or turning heat) produces, that is to say that the feedback compensation device has just solved the influence of lathe transmission chain error, and to the influence that other error the produces fine solution of failing.
Summary of the invention:
The purpose of this utility model provides a kind of digital intelligent feedback thread grinding compensation arrangement, is difficult to eliminate the problem of error when solving on grinding machine grinding threads of lead screw.
The purpose of this utility model realizes as follows: grating reading device and aligning gear are housed on grinding machine, aligning gear is that stepper motor is housed on housing, ball screw assembly, is housed in the housing, the leading screw axial restraint of ball screw assembly,, leading screw is connected by shaft coupling with the stepper motor output shaft, the nut of ball screw assembly, is circumferentially fixing, and this nut is associated with the fork of device on former lathe master screw nut; The grating reading device is mounted in the grating reading head at grinding machine spindle place.Utilize leading screw dynamic Laser detector, carry out detection of dynamic to desiring processing work, and detection curve is analyzed, edits, handled, according to the final precision of workpiece, form new offset data file, offset data is input in the memory data table of feedback compensation device.Add man-hour in feedback, the position signalling that utilizes spindle encoder to provide accesses the leading screw error of corresponding points in the memory data table, delivers to stepper motor driver, is moved by the driver drives stepper motor.The stepper motor output shaft rotates by driving ball-screw, ball-screw nut is moved up and down along fairlead, driving fork by the contact makes former lathe master screw nut make small additional rotation, workbench produces moving axially of trace thus, thereby reaches the purpose of proofreading and correct processing threads of lead screw precision.
The nut front of ball screw assembly, has push rod to withstand on to be fixed in the one side of the fork on the former lathe master screw nut, and the another side of fork is pressed with spring, makes nut make minor rotation by the effect of push rod and spring, thereby reaches the purpose of correcting working table displacement.
This digital intelligent feedback thread grinding compensation arrangement, only need the detection curve of desiring workpiece is analyzed, edits, handled,, form new file according to the final precision of workpiece, to form new file again and deliver to the feedback compensation device, to realize eliminating the purpose of mismachining tolerance.The signal transmission of this feedback compensation device and dynamic Laser somascope, available floppy disk copy, also the available transmission line transmits, and is very convenient.Biao Xian major advantage is in actual applications: (1) can significantly improve the grinding accuracy of ball-screw product, the rate of reducing the number of rejects and seconds, thus reduce cost, boost productivity, for enterprise brings bigger economic benefit; (2) because precision lead screw is the transmission and the setting element of all kinds of machineries and instrument, the raising of its product quality can make machining accuracy of NC machine tool be improved, and impels the generally raising of whole machine-building level; (3) can promote the use of in the middle of the machining control of other class machine components (as gear, worm gear etc.), for the precision of engineering goods provides a valid approach.
